2G cellular module offers upgrade path to 3G, LTE or LPWA

A quad-band GSM/GPRS cellular module, the u‑blox SARA-G450, has optimised power consumption for IoT applications, says u-blox.

The SARA-G450 2G cellular module for machine to machine (M2M) applications, such as utility metering and tracking systems is in the established SARA form factor. The module lets product developers migrate their products to 3G, LTE, or LPWA technology to meet a broad range of environmental and technological requirements.

2G cellular technology offers reliable performance for mobile applications and broad geographical coverage. It has been the technology of choice for machine type connectivity such as fleet management, metering and tracking. While some regions are currently phasing out their 2G network infrastructure, 2G continues to be a viable and popular option for M2M solutions in regions still lacking NB-IoT and LTE Cat M1 networks or where coverage is ‘spotty’. The SARA-G450 targets cost and space-sensitive applications in these markets, says u-blox.

It is pin-compatible with the entire u-blox cellular range, enabling designers to use a single platform and PCB design for designs intended for a variety of air interface technologies, including  2G, 3G, LPWA (LTE Cat M1 and NB1), and high speed LTE. According to u-blox, this also means that product developers can anticipate future upgrades of their applications to move to LTE Cat M1 and NB1 connectivity as soon as they become available in their target markets.

SARA-G450 is a standard grade quad-band GSM/GPRS module that is power-optimised for IoT applications. It can combine with a variety of best-in-class u‑blox GNSS or Bluetooth modules for solutions that integrate positioning, short range and cellular communication. An embedded internet suite facilitates the development of a range of M2M devices.

u‑blox provides positioning and wireless communication technologies for the automotive, industrial, and consumer markets, to allow people, vehicles, and machines determine their precise position and communicate wirelessly over cellular and short range networks. The company portfolio includes chips, modules, and a growing ecosystem of product supporting data services.
